DISC ROTOR : Inspection and Adjustment
INSPECTION
Appearance
Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace it if necessary. See: Brake Caliper/Service and Repair/Removal and
Replacement/Removal And Installation.
Runout
1. Fix the disc rotor to the wheel hub and bearing assembly with wheel nuts (2 points at least).
2. Check the wheel bearing axial end play before the inspection. See: Maintenance/Wheels and Tires/Wheel Hub/Service and
Repair/Procedures/Front Wheel Hub and Knuckle.
3. Inspect the runout with a dial indicator to measure at 10 mm
(0.39 in) inside the disc edge.
Runout : See: Specifications
4. Find the installation position that has a minimum runout by shifting the disc rotor-to-wheel hub and bearing assembly installation position by one
hole at a time if the runout exceeds the limit value.
5. Refinish the disc rotor if the runout is outside the limit even after performing the above operation. [When refinishing, use the Pro-Cut PEM
On-Car brake Lathe (Tool No. 38-PFM90.5) or equivalent.]
CAUTION:
-
Check in advance that the thickness of the disc rotor is wear thickness + 0.3 mm (0.12 in) or more.
-
If the thickness is less than wear thickness + 0.3 mm (0.012 in), replace the disc rotor.
Wear thickness : See: Specifications
Thickness
Check the thickness of the disc rotor using a micrometer. Replace the disc rotor if the thickness is below the wear limit. See: Brake Caliper/Service
and Repair/Removal and Replacement/Removal And Installation.
